The Philadelphia 76ers condemned the racist social media comments directed at Jimmy Butler made by the father of forward Mike Muscala, and Muscala apologized for his dad’s comments in a statement released by the team Saturday.

“Earlier today, I was made aware of inappropriate and offensive social media posts from Bob Muscala, father of Mike Muscala,” Sixers general manager Elton Brand said in the statement. “Simply put, they are unacceptable and in no way reflective of the beliefs of our organization.

“Having known Mike since his rookie year in 2013-14 when we were teammates, I am also certain these posts are in no way reflective of his own personal beliefs. Mike has always been a great teammate and ambassador for the game of basketball, and he has never shied away from using his platform to do good in the community. He has our organization’s full support.”

Posting under the Twitter handle @MuskieBobber, which Bob Muscala says on his web page is his account, the elder Muscala tweeted, “Butler behavior not a ‘dust up’. This is egomaniacal, African American mental illness.”

A person with direct knowledge of the situation also confirmed to USA TODAY Sports that Bob Muscala posted under that Twitter name. The person requested anonymity because they were not authorized to speak publicly about the situation.

Bob Muscala was responding to a headline that read, “The Best Practice Dust Ups in NBA history,” with a photo of Michael Jordan, Butler and Kobe Bryant.

The tweet has been deleted but was captured before the account was deleted entirely.

In one of his first real issues to handle as GM of the Sixers, Brand took a proactive approach and released a statement before the story engulfed the team.

Muscala also denounced his dad’s comments.

“First and foremost, I want to apologize for my father’s offensive social media commentary,” Muscala said. “His comments were uncalled for and inappropriate, and they do not reflect who I am. I’d also like to apologize to the 76ers and my colleagues across the NBA for the distraction my father’s comments caused. I really appreciate the professionalism and support shown by Elton, Coach [Brett] Brown, my teammates and the entire 76ers organization.”

Bob Muscala also made several other tweets aimed at Butler and the Minnesota Timberwolves, who are embroiled in a standoff. Butler wants a trade, and the Timberwolves don’t appear to be willing to trade him or haven’t found the perfect deal.

Butler, who returned to practice Wednesday, reportedly yelled at coaches and teammates per ESPN. Butler told general manager Scott Layden, “You (expletive) need me. You can’t win without me.” He also exchanged words with Karl-Anthony Towns.
